The trial of Brooke Astor's son kicked off this morning with prosecutors arguing that Anthony Marshall was a liar and a thief who'd conspired to steal $200 million from his ailing mother. More importantly, the prosecution indicated that some 60 witnesses could be called to testify—including Barbara Walters, Henry Kissinger, Annette de la Renta, David Rockefeller, former UN secretary general Kofi Annan, New York Public Library head Paul LeClerc, and former Met chief Philippe de Montebello—so there should be plenty of material to keep up the public's attention for what is expected to be a three-month trial.
